Abstract
Embodiments contemplate that the transfer of an Internet Protocol (IP) address from one (e.g. a first) Gateway (GW) to another (e.g. a second) Gateway (GW) may improve the Dynamic Mobility Management (DMM) handling in any network environment, including a dense network environment. Embodiments contemplate a dense network may enable a User Equipment (UE or wireless transmit/receive unit (WTRU)) to be connected to the closest GW while the IP address transfer may enable the usage of a relatively short data path (e.g. perhaps a “shortest” data path), which may be useful in the context of DMM, perhaps even for existing flows. Using the contemplated capability of moving IP addresses may minimize the number of IP addresses allocated and/or the number of tunnels to be maintained.

11. A wireless transmit/receive unit (WTRU) in communication with a wireless communication network, the WTRU comprising:
a processor, configured at least to; connect to a first node of the wireless communication network; obtain a first Internet Protocol (IP) address from the first node; communicate via the first IP address as connected to the first node; initiate a handover to a second node of the wireless communication network; connect to the second node; obtain a second IP address from the second node; and communicate via the first IP address as connected to the second node upon an occurrence of a condition, the condition including one or more characteristics of the first node and one or more characteristics of the second node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 26, 27)

28. A method for communication in a wireless communication network, the method comprising:
-
connecting, by a wireless transmit/receive unit (WTRU), to a first node of the wireless communication network; obtaining, by the WTRU, a first Internet Protocol (IP) address from the first node; communicating, by the WTRU, via the first IP address as connected to the first node; initiating, by the WTRU, a handover to a second node of the wireless communication network; connecting, by the WTRU, to the second node; obtaining, by the WTRU, a second IP address from the second node; and communicating, by the WTRU, via the first IP address as connected to the second node upon an occurrence of a condition, the condition including one or more characteristics of the first node and one or more characteristics of the second node. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
